49ers fans chant ‘Seahawks suck’ during ‘TNF’ postgame show

While Colin Kaepernick and Frank Gore talked with the hosts of “Thursday Night Football” on the field where they just beat the Rams, rowdy 49ers fans behind the TV cameras were heard shouting “Seahawks suck! Seahawks suck!”

QB Kaepernick was talking on set about his team’s effort the past two weeks to recover from their two-loss slump, when the fans — who yelled throughout the live postgame broadcast — let it be known what they think of the Hawks.

Since the Seahawks thrashed the Niners 29-3 at CenturyLink Field on Sept. 15, fans have been bickering. The 49ers fans who made noise about the 12th Man’s “unsportsmanlike” crowd roar didn’t help, and others have denied that a Seahawks-49ers rivalry even exists.

On Thursday night in St. Louis, the Niners showed how dominant they can be when all the pieces work together. San Francisco broke through in the second quarter, putting up 21 unanswered points and rolling over the Rams 35-11 at Edward Jones Dome.

Kaepernick was 15-for-23 with 167 passing yards and two touchdowns, and star receiver Anquan Boldin had 90 yards and a score on five catches. Running back Gore delivered a commanding performance with 153 rushing yards on 20 carries, including a 34-yard touchdown run on fourth-and-inches. Linebacker NaVorro Bowman had two of San Francisco’s fives sacks as the defense curb-stomped St. Louis, holding the Rams to an astounding 18 rushing yards and an inept Sam Bradford to 19-for-41 passing.

San Francisco improved to 2-2 with the first victory of Week 4. St. Louis dropped to 1-3, last in the division for now behind the 1-2 Arizona Cardinals, who are at Tampa Bay on Sunday. Seattle sits atop the NFC West at 3-0 and plays in Houston this weekend.
